10 Reasons to Get More Sleep

10 Reasons to Get More Sleep

Regularly sleeping less than seven hours at night can put your health and safety at risk, which is why it’s essential that you prioritize and protect your sleep daily.

Getting a good night’s sleep is incredibly important for your health. In fact, it’s just as important as eating a balanced, nutritious diet and exercising.

Though sleep needs vary from person to person, most adults require between 7 and 9 hours of sleep per night. Yet, up to 35% of adults in the United States don’t get enough  

This article tells you 9 reasons why you need to get more sleep.

  1. May help you maintain or lose weight

Numerous studies have associated short sleep — defined as sleeping fewer than 7 hours per night — with a greater risk of weight gain and a higher body mass index (BMI)  

In fact, a 2020 analysis found that adults who slept fewer than 7 hours per night had a whopping 41% increased risk of developing obesity. Meanwhile, sleeping longer didn’t increase the  

The effect of sleep on weight gain is believed to be affected by numerous factors, including hormones and motivation to exercise  

For instance, sleep deprivation increases levels of ghrelin and decreases levels of leptin. Ghrelin is a hormone that makes us feel hungry while leptin makes us feel full. This may cause us to feel hungrier and overeat  

This is supported by various studies that have shown that sleep-deprived individuals have a bigger appetite and tend to eat more calories  

What’s more, to compensate for lack of energy, sleep deprivation may make you crave foods that are higher in sugar and fat, due to their higher calorie content  

To make matters worse, feeling tired after a night of too little sleep may leave you feeling unmotivated to hit the gym, go for a walk, or do whichever other physical activity you enjoy.

So, prioritizing sleep may support healthy body weight.

  1. Can improve concentration and productivity

Sleep is important for various aspects of brain function.

Cognition, concentration, productivity, and performance are all negatively affected by sleep deprivation  

A specific study on overworked physicians provides a good example. It found that doctors with moderate, high, and very high sleep-related impairment were 54%, 96%, and 97% more likely to report clinically significant medical errors  

On a similar note, getting enough sleep can improve academic performance in children, adolescents, and young adults  

Finally, good sleep has been shown to improve problem-solving skills and enhance memory performance in both children and  

  1. Can maximize athletic performance

Sleep has been shown to enhance athletic performance.

Numerous studies have shown that adequate sleep can enhance fine motor skills, reaction time, muscular power, muscular endurance, and problem-solving skills  

What’s more, lack of sleep may increase your risk of injury and lower your motivation to exercise  

So, getting enough sleep may be just the thing you need to take your performance to the next level.

  1. May strengthen your heart

Low sleep quality and duration may increase your risk of developing heart disease

One analysis of 19 studies found that sleeping fewer than 7 hours per day resulted in a 13% increased risk of death from heart disease  

Another analysis found that compared with 7 hours of sleep, each 1-hour decrease in sleep was associated with a 6% increased risk of all-cause mortality and heart disease  

What’s more, short sleep appears to increase the risk of high blood pressure, especially in those with obstructive sleep apnea — a condition characterized by interrupted breathing during sleep  

In fact, one study found that people who slept fewer than 5 hours per night had a 61% higher risk of developing high blood pressure than those who slept 7 hours  

Interestingly, excessive sleep in adults — more than 9 hours — was also shown to increase the risk of heart disease and high blood pressure  

  1. Affects sugar metabolism and type 2 diabetes risk

Short sleep is associated with a greater risk of developing type 2 diabetes and insulin resistance — which is when your body cannot use the hormone insulin properly  

In fact, an analysis of 36 studies in over 1 million participants found that very short sleep of fewer than 5 hours and short sleep of fewer than 6 hours increased the risk of developing type 2 diabetes by 48% and 18%, respectively  

It’s thought that sleep deprivation can cause physiological changes like decreased insulin sensitivity, increased inflammation, and hunger hormone changes, as well as behavioral changes like poor decision making and greater food intake — all of which increase diabetes risk  

Plus, sleep deprivation is associated with a higher risk of developing obesity, heart disease, and metabolic syndrome. These factors also increase your risk of  

  1. Poor sleep is linked to depression

Mental health concerns, such as depression, are strongly linked to poor sleep quality and sleeping disorders  

One study in 2,672 participants found that those with anxiety and depression were more likely to report poorer sleep scores than those without anxiety and depression  

In other studies, people with sleeping disorders like insomnia or obstructive sleep apnea also report higher rates of depression than those without  

If you have trouble with sleep and notice your mental health has worsened, it’s important to speak with your healthcare professional.

  1. Supports a healthy immune system

Lack of sleep has been shown to impair immune function  

In one study, participants who slept fewer than 5 hours per night were 4.5 times more likely to develop a cold compared than who slept more than 7 hours. Those who slept 5–6 hours were 4.24 times more likely  

Some data also suggests that proper sleep may improve your body’s antibody responses to influenza vaccines

Recently, preliminary data shows that getting enough sleep before and after receiving a COVID-19 vaccination may improve vaccine efficacy. Still, more research is needed to better understand this possible connection  

  1. Poor sleep is linked to increased inflammation

Poor sleep can have a major effect on inflammation in the body.

Sleep plays a key role in the regulation of our central nervous system. In particular, it’s involved in the stress-response systems known as the sympathetic nervous system and the hypothalamic-pituitary-adrenal (HPA) axis  

Sleep loss, especially from disturbed sleep, is known to activate inflammatory signaling pathways and lead to higher levels of undesirable markers of inflammation, like interleukin-6 and C-reactive protein  

Over time, chronic inflammation can cause the development of many chronic conditions, including obesity, heart disease, certain types of cancer, Alzheimer’s disease, depression, and type 2 diabetes  

  1. Affects emotions and social interactions

Sleep loss reduces your ability to regulate emotions and interact socially.

When we’re tired, we have a harder time controlling emotional outbursts and our behaviors in front of others. Tiredness may also affect our ability to respond to humor and show empathy  

Plus, those who are chronically sleep-deprived are more likely to withdrawal from social events and experience loneliness  

Prioritizing sleep may be a keyway to improve your relationships with others and help you become more social.

If you deal with loneliness or emotional outbursts, don’t be afraid to reach out to a friend, family member, or healthcare professional to get support.  

Lack of sleep can be dangerous

Not getting enough sleep can be dangerous for yourself and others.

When we’re tired, our ability to focus on tasks, reflexes, and reaction times decreases. In fact, being severely sleep-deprived is comparable to having consumed excess alcohol.

Concerningly, the Centers for Disease Control and Prevention (CDC) reports that 1 in 25 people have fallen asleep at the wheel while driving. Those who slept fewer than 6 hours were most likely to fall asleep while driving  

One 2018 study found that people who slept 6, 5, 4, or fewer than 4 hours had a risk of causing a car accident that was 1.3, 1.9, 2.9, and 15.1 times higher, respectively. This study suggests that your risk of a car accident increases significantly with each hour of lost sleep  

Further, the CDC reports that staying awake for more than 18 hours is comparable to having a blood alcohol content (BAC) of 0.05%. After 24 hours, this increases to 1.00%, which is over the legal driving limit  

In addition to increased risks associated with driving, lack of sleep may also increase the risk of workplace injury and errors  

All in all, getting proper sleep is important for everyone’s safety.

The bottom line

Along with nutrition and exercise,taking care of your sleep is one of the pillars of health.

Lack of sleep is associated with many negative health effects, including increased risk of heart disease, depression, weight gain, inflammation, and sickness.

Though individual needs vary, most research suggests that you should get between 7 and 9 hours of sleep per night for optimal health.

Just like you prioritize your diet and physical activity, it’s time to give sleep the attention it deserves.
